No, no... it's gotta be the nForce 590 mobo. It's the only mobo that allows you to run SLI with the Conroe CPU. I'l stick with Maximum PC's list thus far: - Intel Core 2 Extreme X6800 - nForce 590 XLI Intel mobo - 2 GB Corsair DDR2/800 (SLI ready) - PC Power Silencer 750 power supply Videocards: Gotta be nVidia. Gotta be SLI. But which ones? Two 7900 GTXs will set you back about $1,000. Hard drives: Raptors? Or the new 500/750 GB monsters? Both? Hmmm....
